Engineering Economics Calculators
Time value of money, NPV, IRR, depreciation, break-even analysis, loan amortization
Engineering Economics covers time value of money, npv, irr, depreciation, break-even analysis, loan amortization.
This engineering course provides rigorous analysis tools for economics problems encountered in professional practice. Students work through both theoretical derivations and applied numerical examples to build the quantitative skills needed in industry.
The tools and techniques developed in Economics are applied daily by practicing engineers and form essential prerequisites for advanced coursework and professional engineering practice.
Key Concepts
- •Core theory and principles of economics
- •Applied problem-solving using industry-standard methods
- •Quantitative analysis with real engineering units and magnitudes
- •Connections to other engineering disciplines
Prerequisites
Calculus
Most engineering analysis courses require differential and integral calculus.
Introductory Physics
Familiarity with basic mechanics and energy concepts provides context for engineering-level analysis.
Economics Calculators
Time Value of Money Calculator
Solve for PV, FV, PMT, n, or i. Supports ordinary annuity, annuity due, and arithmetic gradient series with cash flow diagram.
NPV / IRR Calculator
Enter initial investment and annual cash flows to compute NPV, IRR (bisection), payback period, and discounted payback. NPV vs discount rate chart.
Break-Even Calculator
Fixed costs, variable cost per unit, and selling price → break-even quantity, revenue, contribution margin, and margin of safety with cost/revenue chart.
Depreciation Calculator
Depreciation schedule using straight-line, declining balance, double declining, MACRS, or sum-of-years digits methods with book value chart.
Cost-Benefit Calculator
Enter annual costs and benefits (up to 20 years). Compute B/C ratio, net benefit, PV of costs and benefits, and cumulative cash flow chart.
Loan Amortization Calculator
Principal, rate, and term → monthly payment, total interest, full amortization schedule, and principal vs interest pie chart.
Rate of Return Calculator
Incremental IRR analysis comparing two alternatives. Computes IRR_A, IRR_B, incremental IRR, NPV at MARR, and preferred alternative.
Effective Interest Rate Calculator
Nominal APR → effective annual rate (APY/EAR) for any compounding frequency including continuous. APR ↔ APY conversion with comparison table.
